To all whom is may concern Be it known that 1, CHARLES Animis- RA LL, ciiizen of the United States of America, residing Boston, in the county of Snfiollr and State of Massachusetts, have invenred certain new and useful improve- 1 merits in Heed-Supports for Telephone-Receivers, of Which the following is a specifloat-ion. i

This invention relates io telephony and, more particularly, to shatbranch of telephony which has to do with supporting means for telephone receivers.

The main olijects of the invention are to provide a supporting head band so constructed as (o grip the head firmly so as to avoid displacement while, at the same time, so distributing the pressure as to avoid all unpleasantness or discomfort to the user; to so connect the receivers to said head band as to permit a quick adjustment of the same either tightly against the car, in light contact therewith or completely removed therefrom Without the necessity of removal of the instrument from she head of the operoior, said adjusiinents being practica y instantaneous; to provide a head support Wire the receivers so hung therefrom as to pernri' u of three adjustments, viz :a vertical ustinent, a universal adjustment about given point, and a rocking adjustment of the receiver upon its horizontal axis; to provide novel means for quickly performing the vertical adjustmentof the receiver;

As will be readily understood from my application for on head supports for telephone receivers, filed F eh. 19, 1913, Serial llo. E9332, which the present invcntion is an improvement, the adjustments heretofore mentioned, and especially that permitting the receiver to be held closely i0 ihe our, in lighb Contact therewith, or; completely removed therefrom will prove a boon io the operator required to use a head supported receiver in that it will permit .lch operator to quickly and easily relieve close pressure upon the ear which is practically constantly maintained in the supports now in use and which results in much unpleasantness to the operator and, in fact, in many instances in positive injury.

Vfich ehe foregoing and such oiher objects in view as may hereinafter more fully appear, my invention consists in the novel arrangementand construction of parts set forth in the appended specifications, more particularly pointed out in the claims, and which are shown in the: cconipanying drawings, \vhercin:

Figure 1 is a perspective view of the device, showing the same in place on the head of an operator. Fig. 2 is a front elevation of the device as the some appears when removed from the head. Fig. 3 is a side elevation. Fig. 4: is a detail sectional view taken on the line l-l of Fig. 3. Fig. 5 is a detail sectional view taken do the line 55 of Fig. Fig. (5 is a detail front'elevution, partly in sectioiuof a modified form of the device. Fig. 7 is a side elevation of said modification. Fig. 8 is a side elevation showing a further modification of the vertical adjusting means. Fig. 9 is a side elevation of a niodilied form of head band. Fig. 10 is a plan view of the same. Fig. 11 is a plan View of still another modification of the head hand. 7

Referring to said drawings by numerals, a head hand 1, of any suitable form and material, but preferably, as here shown, 01 are shape and composed of resilient metal, is provided near the ends thereof with head gripping pads i.

Pads 2 may he of any suitable and convenient form but they are preferably curved, as here shown to conform to the contour of the head with the longer portion of the pad lying to the rear of thehead band and above and back of the ear of the user. The said pads are formed of any suitable nuitcriol such as metal or fiber and may be suitably covered with leather or other suitable material as shown most clearly at 3, Figs. 5, or left uncovered if so desired. These pads may be fastened to head band 1 in any desired manner, but, as here shown, -said pads are provided with square aperturcs' adapted to ulinc with similar apcr-.

tures formed in head band 1 and to receive the square portion 6 of screw 7, which said screw through its engaging nut 8 serves to bind'said pad and head band together and also support the receiver hanger.

The receiver hanger is composed of an elongated metal plate 9 provided with a longitudinal slot 10 adapted to receive the shank of screw 7 for the purpose of adjust- .ably securing said hanger to the head band.

10 Plate 9 is provided withan angularly disposed, bifurcated end 11. Said bifurcations 11 are'provided with alining, circular aper tures 12, said apertures being preferably reamed and adapted to journal a ball 13 placed between said bifurcations. Bifurcations 11 are suitably bored and threaded for the reception of a screw 14 through which the tension of said members upon the ball 13 may be-regulated. Integral with saidv ball,

or otherwise suitably joined thereto is an arm or rod 15 the other end of which is riveted, or otherwise securely fastened to the central point of a suitably bent receiver holding strap 16. Strap 16 is provided with pins '17 securely fastened therein and adapted to enter sockets formed for their reception in the casing of receiver 18.

As can be seen inost clearly in Figs. 1, 2 and 3, the ends of strap 16 project below' the journaling point, of pins 17 so that the .mo-

tion of the receiver about said point is limited by the ends coming in contact with the usual rolled edge 18' of said receiver; while the upper portion 19 of said strap isso formed and placed as to limit the receivers motion in the opposite direction by contact with the aforesaid edge 18. I

In Fig. 6 is shown a modification of the device in which pad 2 has interposed between it and the head band 1 a plate 20; the

'said' three members being riveted, or otherwise suitably joined. Journaled in the angularly disposed ends 21 of plate 20 is a cam lever 22 adapted, to grip the plate 9 for the purpose of adjustably securing the same in place. This permits of a quicker "and easier means of adjustment than the screw and nut heretofore described. Inv said figure is also shown a modification of the means of connecting the receiver. Instead of the Y shaped hanger heretofore described, a flat angle bar 23 is suitably fastened to ball 13 and is secured to the back of the receiver casing 18 by means of screw 24 and nut 25, the receiver being held from turning thereon by astay pin 26 carried by said am 23 and adapted to enter a suitable recess'formed in the receiver casing for its reception.

In Fig. 8 is shown 'a modification of the vertical adjustable means. Ball 13 is' provided with a bore passing through the center thereof, said bore being square'in cross sectlon and adapted to receive the rod 27 which is threaded for a portion of its length the I o remaining portion being square to prevent rotary movement of said rod with relation to the ball 13. A nut 28 is adapted to engage the threaded portion of said rod 27 for the purpose of verticall adjusting the receiver. As will be rea 'ly understoodthe connection of the rod to the receiverfmay be as here shown and as described with relation to the modification of Fig. 6 or it may be that shown in Figs. 1, 2 and 3.

A modification of the head bandl is shown'inFigs. 9, 10 and 11. In this form the band, instead .of crossing the, head in the usual manner,'shown most clearly in Fig. 1, encircles the head. Said band'maybe of any suitable material and may be fastenedby anysuitable means such as the friction buckle 29. This'form of band may also be of resilient material of practically horse,

shoe shape, provided with suitable pressure pads and adapted to encircle the head, with faint sounds to be detected, in which case it will fit the-ear snugly because of itspivotal movement upon the pins 17, or the universal ball-joint means, and it may be quickly released from tight contact, when the sound is too loud for such contact, by a slight touch;-

or again it may bemoved completely away from the ear when not in use and-will remain inthe desiredpositibn y the friction at the ball-joint.
